Reselling News: Amazon Locks In a January 31 Holiday Return Deadline and USPS Will Reprice Shipping Weekly in 2027

Two of this week's headlines move numbers a seller does not get to vote on: how long a completed sale can still be undone, and what the post office charges to move a box. A third one, eBay's quarterly report, lands this afternoon. Here is each item and the action it calls for.

Amazon's holiday return window opens Saturday and does not close until January 31

Amazon set its 2026 holiday return window, and this time it said the timeline is permanent. Anything a customer buys between November 1 and December 31 can be sent back through January 31, 2027. Apple-branded items get a shorter runway and have to be back by January 15. It covers both FBA and seller-fulfilled orders in the US, and it applies automatically, so there is nothing to opt into. Value Added Resource has the details, and PPC Land covered the part that is actually new, which is Amazon saying it will apply this window every year instead of announcing it fresh each fall.

Do the math on what that means. An item sold November 1 under the normal 30-day rule would be final somewhere around early December. Under the holiday window the same sale is still reversible 91 days later. A holiday quarter that looks profitable on December 31 can give a chunk of itself back in January.

What to do: treat November and December Amazon revenue as provisional until February. If you are using Q4 cash to buy Q1 inventory, hold a reserve back rather than spending the whole number. And watch the categories that get gifted and regifted, because those are the ones that come home.

USPS wants to reprice shipping every single week starting in 2027

This is the bigger structural story. USPS is planning a fuel surcharge on domestic packages that updates weekly, calculated as a percentage of base postage, tied to diesel and jet fuel prices published by the Energy Information Administration. Ground Advantage and Parcel Select would track diesel, Priority Mail and Priority Mail Express would track jet fuel. USPS laid out the mechanics in its own fuel surcharge FAQ, and Supply Chain Dive reported the January 2027 start, which lines up with the temporary 8 percent surcharge expiring January 17.

The piece that matters for a small seller is the notice period. Value Added Resource points out that new percentages get published only three to five days before they take effect, and USPS has not said what the opening percentage is, how the formula works, or whether there is a ceiling. FedEx and UPS have run variable fuel surcharges for years, so this is USPS catching up to the rest of the industry, but it ends the era of a postage rate you could count on for a whole quarter.

What to do: stop treating shipping as a fixed line in your pricing. If you sell heavy or bulky items on thin margins, that is the inventory most exposed to a surcharge that can move while the item sits unsold. Build your prices off your worst recent label cost, not your best one.

eBay reports Q3 after the bell today

eBay's Q3 2026 earnings call is scheduled for this afternoon, 2:30 PM Pacific per eBay's investor relations page. It comes a week after the company cut 9 percent of its workforce, and with Depop now folded into the results.

An earnings call is not a policy change, but it is where the next year of policy gets telegraphed. The lines worth listening for are anything about ad load, promoted listing rates, Live investment, and what they say about Depop, because what a public company promises investors in October tends to show up in a seller fee notice later.

What to do: nothing today. Read the seller-facing coverage tomorrow rather than the stock reaction.

What ties these together

Two of these three items share a shape: a cost that arrives after the price is already locked. A return window that runs to January and a label price that moves weekly both punish the same habit, which is pricing off a single good outcome and treating it as the baseline.

Working out how to price around costs that move, and how to read a fee notice before it hits your margin, is the kind of thing that takes a system rather than a tip. That is what we build inside The Income Lab.
